fix: Date extensions tab still shows granted exentions even if reset

[brianjbuck-wgu]

Description

In the new Instructor Dashboard, when an instructor clicks "Reset Extensions" for a learner, the extension record remains visible in the "Granted Extensions" table on the Instructor Dashboard's Date Extensions tab. The table is intended to display only active extensions, but reset extensions still appear because the backend API returns them.

Fixes:

• Fix: Reset extensions remain visible in "Granted Extensions" table #38393
• Fix: Reset extensions remain visible in "Granted Extensions" table frontend-app-instructor-dashboard#160

Other information

• No database migrations required
• No dependencies on other changes

Pull request overview

Fixes the instructor “Date Extensions” endpoint so that revoked/reset due date extensions no longer appear in the “Granted Extensions” list, aligning the backend results with the UI expectation from the linked issues.

Changes:

• Filter out “reset” extensions in UnitExtensionsView.get_queryset when the override date is None or matches the original due date.
• Add test coverage to ensure reset extensions are excluded while legitimate extensions remain visible.

Overall, it looks good. Just a couple of suggestions

[wgu-taylor-payne]

Looks good overall. I've left a couple of small comments. Is this something that should ultimately be moved into edx-when though? In that case we might want to 1) look at making those changes or 2) adding an issue on edx-when and leaving a comment with the issue number where we do this filtering.

[brianjbuck-wgu]

@wgu-taylor-payne, I did consider making the upstream change to edx-when, but I am not sure what the downstream affects would be especially this close to the cutoff for the verawood release.

Yeah, that makes sense. Could you at least bring this up in an issue on edx-when so it can be investigated further at some point?

[diana-villalvazo-wgu]

tested on UI and works as expected 👍
